Im curious why

Noone had any advice about running Cyclone II based boards off rechargeable batteries? Is there something I dont know where it's a bad idea?

National Semi regulators sounds like linear regulators. Switchers are much better for power limited applications. I have power limited Altera designs, and I use the LTC3415 for core voltages for its efficiency. (You have to pay a little more attention to power supply noise.) Linear Tech also has an easier to use LTM series. Also easy to use is a series from MuRata that specifically targets FPGA voltages, MPD family.
